MANILA — “CSI” actress Marg Helgenberger may be right after all when she described Canadian pop sensation Justin Bieber as “kind of a brat.”

According to the Manila Bulletin, Manila may have just gotten a taste of Bieber’s alleged infamous reputation.

The 17-year old singer, who left Manila Wednesday morning following a sold out concert at SM Mall of Asia Concert Grounds, reportedly exhibited unfavorable behavior towards his waiting fans at the Ninoy Aquino International Airport (NAIA), according to reports by ABS-CBN and GMA.

In videos aired on GMA’s “24 Oras” Wednesday and on “Unang Hirit” the following day, Bieber can be seen walking hurriedly and, at one point, asking his fans to get out of his way.

ABS-CBN’s “Umagang Kay Ganda” showed the diminutive pop star telling a cameraman, “Can you back up, bro? Thank you,” when the latter took footage of him up close while the singer and company were getting their luggage from the x-ray scanner.

Following Bieber’s May 10 concert, Hollywood blogger Perez Hilton and Hollywood entertainment TV show “TMZ” wrote in their respective websites that Bieber had already been feeling unwell even before arriving in the country.

Bieber was said to have been diagnosed last week with a “bad chest infection,” and was “so ill” during his concert that he went backstage in between songs to vomit.

Many of Bieber’s fans — known as Beliebers — defended the singer and attributed this display of attitude to his health condition.

In any case, Bieber described his Manila show on his Twitter account as “great but tough.”

Meanwhile, the same “UKG” report said that the singer was a no-show at his concert’s after party held at the Seventh High Lounge in Taguig Tuesday night.
